It is a figure which shows the light incontinence pad for men in a folded state. It is a figure which shows another example of a light incontinence pad for men. It is a figure which shows another example of a light incontinence pad for men.

FIG. 1 is a plan view showing a state in which the men's light incontinence pad 1 according to the embodiment of the present invention is opened. The men's light incontinence pad 1 (hereinafter, simply referred to as "light incontinence pad 1") is attached to the inside of the underwear worn by the wearer (that is, the wearer's side) to collect excrement such as urine from the wearer. It is an absorbent article that receives. The men's light incontinence pad 1 may be attached to the inside of a disposable diaper or the like worn by the wearer. In FIG. 1, the light incontinence pad 1 is drawn with the surface in contact with the wearer facing the front when worn.

2 and 3 are cross sections of the light incontinence pad 1 cut in a plane perpendicular to the longitudinal direction (that is, the vertical direction in FIG. 1) at the positions II-II and III-III shown in FIG. 1, respectively. It is a figure. In FIGS. 2 and 3, for convenience of illustration, each configuration of the light incontinence pad 1 is drawn separated in the thickness direction.

As shown in FIGS. 1 to 3, the light incontinence pad 1 is arranged on a sheet-shaped main body 2 extending in the longitudinal direction and both sides of the main body 2 (that is, both sides in the width direction perpendicular to the longitudinal direction). It is provided with a pair of side seats 3 to be formed. The main body 2 includes a liquid-permeable top sheet 21, a water-repellent or liquid-impermeable back sheet 23, a sheet-shaped absorbing core 22, and a water-absorbing paper 24. The absorption core 22 is arranged between the top sheet 21 and the back sheet 23. The water absorbing paper 24 is arranged between the absorbing core 22 and the back sheet 23. In FIG. 1, the broken line showing the outline of the absorption core 22 is made thicker than the broken line showing the outline of the water absorbing paper 24 in order to facilitate the understanding of the figure. In FIG. 1 in which the light incontinence pad 1 is viewed in a plan view, the entire water absorbing paper 24 is located inside the outer peripheral edge of the main body 2, and the entire absorbing core 22 is located inside the outer peripheral edge of the water absorbing paper 24.

As shown in FIGS. 2 and 3, the top sheet 21 covers the main surface of the absorption core 22 on the wearer side. The water absorbing paper 24 covers the other main surface of the absorbing core 22, that is, the main surface opposite to the wearer. The back sheet 23 covers the surface of the water absorbing paper 24 opposite to the absorbing core 22, that is, the surface opposite to the wearer. The top sheet 21 is joined to the water absorbing paper 24 by a hot melt adhesive or the like around the absorbing core 22.

The top sheet 21 is a liquid-permeable sheet member that quickly captures the water content of excrement from the wearer and moves it to the absorption core 22. The absorption core 22 absorbs the moisture that has passed through the top sheet 21 and quickly fixes it. The water absorbing paper 24 absorbs the moisture that has passed through the absorbing core 22. The back sheet 23 prevents the moisture that has reached the back sheet 23 from seeping out to the outside of the main body 2. Details of the absorbing core 22 and the water absorbing paper 24 will be described later.

In the light incontinence pad 1, the top sheet 21, the side sheet 3, and the back sheet 23 form a sheet laminate 20 that defines the outer shape of the main body 2. The sheet laminate 20 has a shape extending in the longitudinal direction like the main body 2. As will be described later, when the wearer wears the light incontinence pad 1, one end (upper end in FIG. 1) of the sheet laminate 20 in the longitudinal direction is below the wearer as the front end 11. Contact the abdomen. Further, the other end portion (lower end portion in FIG. 1) of the sheet laminated body 20 faces the crotch portion of the wearer as the crotch lower end portion 12. Actually, the portion of the sheet laminate 20 on the front end 11 side in the longitudinal direction, that is, the portion including the front end 11 when the sheet laminate 20 is approximately bisected in the longitudinal direction is the male wearer. It becomes the front portion 110 that comes into contact with the vessel. Depending on the structure of the light incontinence pad 1, the side sheet 3 may be omitted, and the sheet laminate 20 may be formed by the top sheet 21 and the back sheet 23.

The width of the sheet laminate 20 in the width direction changes along the longitudinal direction, and the front end portion 11 includes a portion where the width of the sheet laminate 20 is maximized. The width of the sheet laminate 20 gradually decreases from the front end portion 11 toward the crotch lower end portion 12. For example, each side edge of the sheet laminated body 20 between the front end portion 11 and the crotch lower end portion 12 is linear, and the width of the sheet laminated body 20 is linear from the front end portion 11 to the crotch lower end portion 12. Decreases to. As described above, in the sheet laminated body 20, the width of the crotch lower end portion 12 in the width direction is smaller than the width (maximum width) of the front end portion 11. The shape of the sheet laminate 20 can also be regarded as a substantially triangular shape.

As shown in FIGS. 1 to 3, the pair of side seats 3 cover approximately the entire length of the main body 2 in the longitudinal direction on both side surfaces of the main body 2. Each side seat 3 includes a side seat main body 31 and a side wall elastic member 32. As shown in FIGS. 2 and 3, the side seat main body 31 is bent along a folding curve 39 over the entire length in the longitudinal direction. Of the side sheet main body 31, the portion on one side of the folding curve 39 is referred to as "side wall fixing portion 33", and the portion on the other side of the folding curve 39 is referred to as "side wall portion 34".

The side wall fixing portion 33 is arranged on the side portion of the main body portion 2 over an approximately overall length in the longitudinal direction, and is hot melted on the wearer side surface (top sheet 21, water absorbing paper 24, back sheet 23) of the main body portion 2. It is joined with an adhesive or the like. As shown in FIG. 1, the edge of the side wall fixing portion 33 other than the folding curve 39 overlaps with the edge of the main body 2 (the edge of the sheet laminated body 20), and the entire side portion of the main body 2 is the side wall fixing portion. Covered by 33. That is, the surface of the light incontinence pad 1 on the wearer side is the surface of the side seat body 31.

The side wall portion 34 is a portion continuous from the side wall fixing portion 33 on the folding curve 39, and extends over the entire length of the main body portion 2 in the longitudinal direction on the side portion of the main body portion 2. At each end 341 of the side wall 34 in the longitudinal direction (hereinafter, referred to as "side wall end 341"), as shown in FIG. 2, the side wall 34 is folded in half and overlapped with the side wall fixing portion 33. The overlapping portions of the side wall portions 34 are joined to each other by a hot melt adhesive or the like, and these portions are joined to the side wall fixing portion 33 by a hot melt adhesive or the like. In FIG. 1, parallel diagonal lines are attached to each side wall end portion 341. The two side wall end portions 341 overlap the front end portion 11 and the crotch lower end portion 12 of the sheet laminated body 20, respectively.

As shown in FIGS. 1 and 3, a side wall elastic member 32 extending in the longitudinal direction is joined to the tip end (free end) of the side wall 34 in an extended state by a hot melt adhesive or the like. As the side wall elastic member 32 contracts, the side wall 34 stands up in a Z shape from the main body 2 toward the wearer between the two side wall end portions 341 (the tip of the side wall 34 is the main body). (Distance from the part 2 to the wearer side), it becomes a three-dimensional gather. The pair of three-dimensional gathers suppress the leakage of urine from both sides of the light incontinence pad 1.

As the above-mentioned hot melt adhesive, polyolefin-based adhesives, rubber-based adhesives, vinyl acetate-based adhesives and the like are used. The top sheet 21, the water absorbing paper 24 and the back sheet 23 may be bonded, and the side sheet 3 and the main body 2 may be bonded by another bonding method (for example, heat bonding or ultrasonic bonding). .. The same applies to other parts to be joined using a hot melt adhesive.

As the top sheet 21, for example, a liquid-permeable non-woven fabric formed of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) whose surface is hydrophilically treated with a surfactant is used. The non-woven fabric is, for example, a point-bonded non-woven fabric, an air-through non-woven fabric, or a spun-bonded non-woven fabric. As the top sheet 21, a non-woven fabric (for example, spunlace non-woven fabric) formed of hydrophilic fibers such as cellulose, rayon, and cotton may be used.

The backsheet 23 includes a water-repellent or liquid-impermeable non-woven fabric formed of hydrophobic fibers (for example, spunbonded non-woven fabric, melt-blow non-woven fabric, SMS (spun-bond, melt-blow, spun-bond) non-woven fabric), water-repellent or water-repellent or non-woven fabric. A liquid-impermeable plastic film or a laminated sheet in which one of the non-woven fabrics and the plastic film is laminated is used. From the viewpoint of preventing stuffiness of the light incontinence pad 1 and improving the comfort of the wearer, the plastic film used in the back sheet 23 is preferably one having moisture permeability (breathability).

As the side sheet main body 31, a water-repellent or liquid-impermeable non-woven fabric (for example, spunbonded non-woven fabric, melt-blown non-woven fabric, SMS non-woven fabric, etc.) formed of hydrophobic fibers is used. As the side wall elastic member 32, for example, a polyurethane thread, a band-shaped polyurethane film, a thread-shaped or band-shaped natural rubber, or the like is used, and in the light incontinence pad 1 shown in FIG. 1, a polyurethane thread is used.

Next, the details of the absorbing core 22 and the water absorbing paper 24 will be described. As shown in FIGS. 2 and 3, the absorption core 22 includes a plurality of absorption sheets 220. In one example of the light incontinence pad 1, two absorbent sheets 220 having the same structure are provided and are accurately stacked in the thickness direction (vertical direction of FIGS. 2 and 3). As will be described later, the outer shape of each absorbing sheet 220 is rectangular. When the light incontinence pad 1 is viewed in a plan view as shown in FIG. 1, the outer shape of the absorption core 22 matches the outer shape of the absorption sheet 220 and is rectangular. In the following description, when the two absorbent sheets 220 shown in FIGS. 2 and 3 are distinguished, the absorbent sheet 220 in contact with the top sheet 21 is referred to as an "upper absorbent sheet 220", and the absorbent sheet in contact with the water absorbing paper 24 is referred to as "upper absorbent sheet 220". 220 is called "lower absorption sheet 220". The absorption core 22 may be provided with only one absorption sheet 220.

Each absorbent sheet 220 includes a liquid-permeable upper layer sheet 221, a liquid-permeable lower layer sheet 222, and a highly absorbent material layer 223. The upper sheet 221 is arranged between the top sheet 21 and the lower sheet 222. The lower sheet 222 is arranged between the upper sheet 221 and the back sheet 23. The highly absorbent material layer 223 is a layer composed of the highly absorbent material 224. In FIGS. 2 and 3, the highly absorbent material 224 is abstractly indicated by white circles. The highly absorbent material layer 223 is arranged between the upper layer sheet 221 and the lower layer sheet 222, and is fixed to one or both by a hot melt adhesive or the like. The highly absorbent material layer 223 comes into contact with both the upper layer sheet 221 and the lower layer sheet 222 (including the case where they come into contact with each other via an adhesive). The upper sheet 221 and the lower sheet 222 are overlapped and joined to each other in a region where the highly absorbent material 224 is not present. In the preferable absorbent sheet 220, in principle, only the highly absorbent material 224 is present between the upper layer sheet 221 and the lower layer sheet 222 except for the adhesive.

FIG. 4 is a plan view showing the absorption sheet 220. The outer shape of each absorbing sheet 220 is a rectangle (rectangle) long in the longitudinal direction. The upper layer sheet 221 and the lower layer sheet 222 also have a shape extending in the longitudinal direction. The absorption sheet 220 is provided with a plurality of material presence regions 225 and a plurality of material absence regions 226. In each material presence region 225, the highly absorbent material 224 is arranged between the upper layer sheet 221 and the lower layer sheet 222. That is, the highly absorbent material 224 is fixed in the plurality of material existence regions 225. In FIG. 4, the material existence region 225 is shaded in parallel.

The plurality of material existence regions 225 have a strip shape extending substantially parallel to each other in the longitudinal direction, and are arranged so as to be separated from each other in the width direction. That is, the absorption sheet 220 is provided with a plurality of material existence regions 225 arranged in a stripe shape extending in the longitudinal direction. In the example of FIG. 4, the widths (widths in the width direction) of the plurality of material existence regions 225 are equal to each other. For example, the basis weights (weights) of the highly absorbent material 224 in the plurality of material existence regions 225 are approximately equal.

The plurality of material absence regions 226 are regions in the absorption sheet 220 excluding the plurality of material presence regions 225. The plurality of material-absent regions 226 are strip-shaped, each extending along the longitudinal direction. In the example of FIG. 4, the width of each material absence region 226 in the width direction is smaller than the width of the material presence region 225. Also, the widths of the plurality of material absent regions 226 are equal to each other. The plurality of material absence regions 226 and the plurality of material presence regions 225 are arranged alternately in the width direction.

In each material absent region 226, there is no highly absorbent material between the upper sheet 221 and the lower sheet 222. In the material absent region 226, it is preferable that the upper layer sheet 221 and the lower layer sheet 222 are joined to each other by a joining method that does not use an adhesive, such as heat fusion joining or joining by embossing. In the material absent region 226, the upper layer sheet 221 and the lower layer sheet 222 may be partially unbonded. The material absent region 226 may be a region containing a small amount of the highly absorbent material, that is, a region in which the density of the high absorbent material 224 is lower than that of the material present region 225 (material low density region).

The upper layer sheet 221 and the lower layer sheet 222 of the absorbent sheet 220 are formed of hydrophobic fibers (polypropylene, polyethylene, polyester, polyamide, nylon, etc.) whose surfaces are hydrophilically treated with a surfactant, as in the case of the top sheet 21, for example. A liquid-permeable non-woven fabric is used. The non-woven fabric is, for example, a point-bonded non-woven fabric, an air-through non-woven fabric, or a spun-bonded non-woven fabric. Further, as the upper layer sheet 221 and the lower layer sheet 222, a non-woven fabric (for example, a spunlace non-woven fabric) formed of hydrophilic fibers such as cellulose, rayon, and cotton may be used. As the upper layer sheet 221 and the lower layer sheet 222, a tissue, a plastic film having a plurality of openings, or the like may be used.

As the highly absorbent material 224, for example, a granular super absorbent polymer (SAP (Super Absorbent Polymer)) or a fibrous super absorbent fiber (SAF (Super Absorbent Fiber)) is used. The highly absorbent material 224 is, in principle, formed of a polymer and does not contain pulp.

The preferred absorption core 22 includes only one or more absorption sheets 220 and does not include a fiber assembly layer for water absorption in which pulp fibers and the like are aggregated. That is, in the preferred light incontinence pad 1, the absorption core 22 of Palpress (so-called polymer sheet) is used. The thickness of such an absorption core 22 is, for example, 5 mm (mm) or less, and 1 mm or more. The upper absorption sheet 220 and the lower absorption sheet 220 may have different structures from each other. For example, the positions of the plurality of material existence regions 225 in the width direction may differ between the upper absorption sheet 220 and the lower absorption sheet 220.

Here, when the light incontinence pad 1 is viewed in a plan view as shown in FIG. 1, the region around the absorption core 22 in the sheet laminate 20 is referred to as an "absence region of the absorption core 22" or a "core absence region". Call. As described above, the absorption core 22 is rectangular, and the front end portion 11 includes a portion where the width of the sheet laminate 20 is maximized. Therefore, there are relatively large core-absent regions on both sides of the front end 11.

The water absorbing paper 24 is arranged between the lower layer sheet 222 of the lower absorbing sheet 220 and the back sheet 23, and covers the absorbing core 22 from the back sheet 23 side (see FIGS. 2 and 3). As shown in FIG. 1, the water-absorbent paper 24 extends in the longitudinal direction from the front end portion 11 to the crotch lower end portion 12, and the length of the water-absorbent paper 24 in the longitudinal direction is larger than the length of the absorption core 22. The width of the water absorbing paper 24 in the width direction is larger than the width of the absorbing core 22 at any position in the longitudinal direction, and the entire absorbing core 22 is covered by the water absorbing paper 24 from the back sheet 23 side.

The water-absorbent paper 24 includes a portion 241 having a constant width in the width direction and a portion 242 having a width larger than that portion 241. Hereinafter, these portions 241,242 are referred to as "narrow portion 241" and "wide portion 242", respectively. The wide portion 242 overlaps the front end portion 11 of the sheet laminated body 20, and the narrow portion 241 overlaps the crotch lower end portion 12. That is, the width of the water-absorbent paper 24 at the crotch lower end portion 12 is smaller than the width of the water-absorbent paper 24 at the front end portion 11. The width of the water absorbing paper 24 is maximum at the front end portion 11. As described above, a relatively large core-absent region is located on both sides of the front end portion 11, and the wide portion 242 of the water-absorbent paper 24 overlaps the core-absent region.

The position in the longitudinal direction where the width of the water absorbing paper 24 is maximum is substantially the same as the position where the width of the sheet laminate 20 is maximum. As described above, the width of the sheet laminate 20 decreases linearly from the front end portion 11 toward the crotch lower end portion 12. In the water-absorbent paper 24, the width of the wide portion 242 gradually decreases from the position in the longitudinal direction where the width becomes maximum toward the narrow portion 241, and the amount of decrease is larger than the amount of decrease in the width of the sheet laminate 20. .. Therefore, in the portion of the wide portion 242 on the narrow portion 241 side, the distance between the side edge and the side edge of the sheet laminate 20 gradually increases as the narrow portion 241 approaches in the longitudinal direction.

Here, in each side portion of the sheet laminated body 20, the region 201 between the side edge of the sheet laminated body 20 and the side edge of the water absorbing paper 24 is not arranged because neither the absorbing core 22 nor the water absorbing paper 24 is arranged. It can be regarded as an absorbent region. Further, the non-absorbent region 201 is preferably composed of a laminated body of the side sheet 3 and the back sheet 23 without the top sheet 21 being arranged. The width of the non-absorbent region 201 in the width direction gradually increases from the position in the longitudinal direction where the width of the sheet laminate 20 and the water-absorbent paper 24 is maximum toward the boundary position between the wide portion 242 and the narrow portion 241. , Maximum at the boundary position. The width of the non-absorbent region 201 at the position where the width is maximum is preferably 15 mm or more because it is easy to pinch.

The water-absorbent paper 24 is formed of, for example, pulp fibers or the like. The basis weight of the water-absorbent paper 24 is larger than the basis weight of the non-woven fabric constituting the top sheet 21 and the back sheet 23. The basis weight of the water-absorbent paper 24 is, for example, 20 g / m ² or more and 45 g / m ² or less, preferably 30 g / m ² or more and 40 g / m ² or less. If it is 20 g / m ² or more, the water absorption amount and rigidity can be obtained, while ^{if it is 45 g / m 2} or less, the wet back of urine from the water absorption paper 24 to the top sheet 21 can be suppressed. The thickness of the water absorbing paper 24 is smaller than the thickness of the absorbing core 22.

FIG. 5 is a diagram showing a light incontinence pad 1 in a folded state. The light incontinence pad 1 is housed in a predetermined packaging bag 91 (indicated by a broken line in FIG. 5) in a folded state. When the light incontinence pad 1 is folded, the light incontinence pad 1 is on the top sheet 21 side, that is, on the top sheet 21 side with two folding curves F1 and F2 (indicated by a alternate long and short dash line in FIG. 1) perpendicular to the longitudinal direction. The sheet 21 is bent so as to be inside. One folding curve F1 is provided near the boundary position between the wide portion 242 and the narrow portion 241 in the front portion 110, and the other folding curve F2 is a position separated from the folding curve F1 toward the crotch lower end portion 12 side. It is provided in.

In the preferred light incontinence pad 1, an adhesive is applied to the surface of the back sheet 23 opposite to the top sheet 21, and the surface of the back sheet 23 is a strip-shaped film that covers substantially the entire back sheet 23. Is affixed. The light incontinence pad 1 is folded toward the top sheet 21 along two folding curves F1 and F2 with the film attached. By joining each side portion of the film folded in three together with the light incontinence pad 1 by a predetermined joining method, the light incontinence pad 1 is housed in the packaging bag 91 formed of the film. The light incontinence pad 1 folded together with the film may be housed in the packaging bag 91 formed in advance in the shape of a bag. The light incontinence pad 1 may be made attachable to underwear by a tape piece or the like of an adhesive tape (double-sided adhesive tape).

When the wearer wears the light incontinence pad 1, the light incontinence pad 1 is taken out from the packaging bag 91, and the film attached to the back sheet 23 is peeled off. Subsequently, the light incontinence pad 1 is attached to the inner surface of the underwear by the adhesive of the back sheet 23 in a state where the underwear worn by the wearer is shifted downward (toe side). At this time, in the underwear, the front portion 110 is arranged at a position facing the wearer's male genitalia when worn, and the crotch lower end portion 12 is arranged at a position facing the wearer's crotch portion. Then, by pulling the underwear upward with respect to the wearer, the light incontinence pad 1 is worn by the wearer (that is, the underwear to which the light incontinence pad 1 is attached is worn).

In the absorption core 22 of the light incontinence pad 1, a high absorption material layer 223 composed of a high absorption material 224 is provided between the upper layer sheet 221 and the lower layer sheet 222, and is used for water absorption in which pulp fibers and the like are aggregated. No fiber assembly layer is provided. As a result, the absorption core 22 can be made thinner, and it is possible to make it difficult to tell from the appearance of the wearer wearing the clothing that the wearer is wearing the light incontinence pad 1. In addition, it is possible to prevent the wearer from feeling uncomfortable due to the light incontinence pad 1 around the male genitalia.

Since both sides of the front end portion 11 are absent regions of the absorption core 22, it is possible to prevent the both sides from becoming bulky or stiff, and the appearance of the wearer is light. It is possible to make it more difficult to understand that the incontinence pad 1 is worn. Further, as will be described later, even when the highly absorbent material 224 of the absorption core 22 absorbs the urine excreted by the wearer and swells, the swelled absorption core 22 is applied to the lower abdomen of the wearer. It is possible to suppress the pressure caused by.

In the light incontinence pad 1, one folding curve F1 is provided in the front portion 110 when it is housed in the packaging bag 91, and the light incontinence pad 1 is habituated to protrude toward the back sheet 23 in the folding curve F1. ing. Therefore, when the wearer wears the light incontinence pad 1, the portion of the main body 2 facing the wearer's male genitalia projects to the side opposite to the wearer. As a result, it is possible to further suppress the occurrence of discomfort due to the light incontinence pad 1 around the male genitalia in the wearer. In the sheet laminated body 20, since the width of the crotch lower end portion 12 in the width direction is smaller than the width of the front end portion 11, it is possible to prevent the wearer from causing discomfort due to the light incontinence pad 1 in the crotch portion. can.

When urine is excreted from the wearer's male genitalia, the urine is received in the anterior portion 110 in principle, passes through the top sheet 21 and reaches the absorption core 22. Urine is absorbed by the highly absorbent material 224 in the plurality of material presence regions 225, and the highly absorbent material 224 swells. At this time, since urine diffuses to some extent in the longitudinal direction through the material absent region 226, a wide range of highly absorbent material 224 in the anterior portion 110 can be used for urine absorption.

After a certain amount of urine has been excreted by the wearer and the highly absorbent material 224 of the anterior portion 110 has swelled, a longitudinal groove extends in the material absent region 226 between the adjacent material present regions 225. It is formed. Then, when urine is further excreted by the wearer, the urine is efficiently diffused in the longitudinal direction (mainly toward the lower end of the crotch 12 side) through the groove, and is highly absorbed over a wide range in the light incontinence pad 1. The sex material 224 can be used for the absorption of urine (as well as when a material low density region is provided).

In the light incontinence pad 1, the width of the non-absorbent region 201 is maximized at a predetermined position between the front end portion 11 and the crotch lower end portion 12 in the longitudinal direction. Therefore, after using the light incontinence pad 1, the wearer (or caregiver) does not pick the non-absorbent region 201 at the predetermined position (without picking the absorbent core 22 containing urine or the water-absorbing paper 24). ), The light incontinence pad 1 can be easily removed from the underwear. By bending the non-absorbent region 201 toward the top sheet 21 along the side edge of the water-absorbent paper 24, the non-absorbent region 201 can be used as a simple side wall portion.

In the light incontinence pad 1, the water absorbing paper 24 can be omitted. In this case, the portion of the absorption core 22 absent region on both sides of the front end portion 11 is formed only by the side seat main body 31, the top sheet 21, and the back seat 23. As a result, the rigidity of the portion is lowered, and the portion is bent unnecessarily, which may cause a sense of discomfort in the wearer.

On the other hand, in the preferred light incontinence pad 1, the water absorbing paper 24 is provided between the absorbing core 22 and the back sheet 23, and a part of the water absorbing paper 24 is provided in the absent region of the absorbing core 22 on both sides of the front end portion 11. Overlap. As a result, it is possible to secure a certain degree of rigidity at each side portion of the front end portion 11, and it is possible to maintain a state in which the front end portion 11 is appropriately spread in the width direction. As a result, it is possible to prevent the wearer from feeling uncomfortable due to bending of the portion of the region.

The light incontinence pad 1 can be deformed in various ways.

As shown in FIG. 6, in the absorption core 22, a region A1 in which a plurality of absorption sheets 220 are provided in an overlapping manner and a region A2 in which a smaller number of absorption sheets 220 are provided than the region A1 may be set. Preferably, the region A1 overlaps the front portion 110 of the sheet laminate 20 and the region A2 overlaps the other portion of the sheet laminate 20. As described above, the manufacturing cost of the light incontinence pad 1 can be reduced by stacking more absorption sheets 220 than other portions only in the front portion 110 where a large absorption amount is required.

Depending on the design of the light incontinence pad 1, the absorption core 22 may have a shape other than a rectangle. Further, depending on the amount of urine absorbed by the light incontinence pad 1, the absorption core 22 may be provided only in the front portion 110. In the absorption sheet 220, the pattern of the material presence region 225 may be changed as appropriate.

As shown in FIG. 7, in the light incontinence pad 1, the structure of the pair of side seats 3 may be changed. In the light incontinence pad 1 of FIG. 7, bending of the side seat main body 31 on the folding curve 39 (see FIG. 2) is omitted. Further, the folding of the side wall portion 34 related to the formation of the side wall end portion 341 is also omitted, and the portion of the side seat main body 31 corresponding to the side wall end portion 341 is joined to the main body portion 2 in an extended state. In the side seat main body 31, the portion and the side wall fixing portion 33 are joined to the main body portion 2 as an outer edge portion 35. When the peripheral edge portion 29 of the main body portion 2 is referred to as the "main body peripheral edge portion 29", the outer edge portion 35 of each side seat main body 31 is joined to a portion on one side of the main body peripheral edge portion 29 in the width direction. In FIG. 7, parallel diagonal lines (parallel diagonal lines having a wider interval than the joint portion 361 described later) are provided with respect to the outer edge portion 35.

When the portion 36 of the peripheral edge portion of each side seat main body 31 excluding the outer edge portion 35 is referred to as the “inner edge portion 36”, the inner edge portions 36 of the pair of side seat main bodies 31 overlap each other along the longitudinal direction. Of these inner edge portions 36, the portions overlapping the front portion 110 are not joined to each other, and an opening 38 is formed between these portions. The remaining portions of the inner edge portion 36 are joined to each other as a joint portion 361, and a bag-shaped portion 37 is formed between the pair of side seat main bodies 31 and the main body portion 2. In FIG. 7, the joint portion 361 is provided with a parallel diagonal line having a narrower interval than the outer edge portion 35.

With the above structure, the cover portion 30 that covers the surface of the main body portion 2 on the top sheet 21 side is realized by the pair of side seats 3. In the cover portion 30, an opening 38 is formed in a portion on one side in the longitudinal direction (a portion on the front end 11 side), and a bag-shaped portion 37 is formed in a portion on the other side (a portion on the crotch lower end 12 side). NS. In the light incontinence pad 1 of FIG. 7, by inserting a male genitalia into the opening 38, it is possible to prevent the excreted urine from leaking to the outside of the light incontinence pad 1. Further, even when a large amount of urine is excreted, it is possible to prevent the urine from returning to the wearer side by holding the urine by the bag-shaped portion 37. The position and shape of the opening 38 in the cover portion 30 may be arbitrarily changed.

The above-described embodiment and the configurations in each modification may be appropriately combined as long as they do not conflict with each other.
